I recently followed a youtube tutorial and i have now got a static IP address for my router -- does that mean that no other IP address can use my wireless signal.
absolutely NOT.
Just for clarity, every
router has two addresses
- WAN side: and your ISP will assign that address and it may change, ergo it is seldomly static
- Lan side: which is set in the router configuration page and while it may be any valid IP address 255 < x < 0 (ie not 255 and not 0) and this means it IS static
but our systems connected to that router have DHCP assigned or STATIC addresses. Normally we don't need systems with static, but there are places where it is handy, eg a local server or a MAC to IP address reservation.
I checked in cmd recently and it is still DHCP enabled can you tell me how to enable MAC address filtering please.
First, count how many network devices you have and include any printers or NAS devices attached directly to the router - - add two = X
Secondly, restrict the DHCP range of your router X. If the router is a x.x.x.1
and the range is 5, then the DHCP range is set to 100-106. When all devices are active,
the DHCP can not assign any more and thus your router will not accept another new connection.
Third, if you have a WiFi router and use wired connections as well then
- use the MAC address mapping to set wired devices 2-6
- Let the WiFi devices map addresses from 11-Y
where Y-11 is the number of WiFi devices you want to allow
This results in Wired systems in the range x.2 -> x.6
WiFi devices x.11 -> x.Y
and any rouge devices will always be x.100 -> x.106
and you can ensure these can't access any of your systems by firewall rules
disallowing anything x.100 and up
If your WiFi is properly encrypted, then there will Never be anything at x.100->x.254
